Continuity: In their first night at the new house the Beardsley's lose power completely. When the doctor arrives (Tom Bosley) he rings the electric doorbell.

Visible crew/equipment: You can see a cameraman reflected in the school bus window as it drives off.

Continuity: When Helen and Frank are walking home after their first date you can see that they are surrounded by people. When the shot changes all the people have disappeared and Helen and Frank are almost completely alone.

Plot hole: In the scene after Frank talks to Helen in the dispensary about Louise, Frank decides to look Helen up in the phone book and ask her to dinner. Considering Helen had only recently moved to San Francisco, it's amazing how quickly she became listed.

Continuity: When Helen and Frank are out on their first date, Helen loses her slip in the bar and Frank retrieves it. After that, Helen's slip mysteriously disappears because she is obviously not wearing it (since the girls cut her dress, she would've had to have pinned it back up or else it would be visible). Also, Helen's purse is too small to stuff it into and Frank didn't bring anything to carry it in.

Factual error: When Darryl is trying to convince Helen to go on the blind date and she gives him a shot, the shot should have been in the shoulder muscle, not the vein.

Continuity: A bottle of ketchup on the lazy Susan (beside the shorter bottle of chili sauce) keeps appearing and disappearing between shots, prior to the dinner starting.

Continuity: Envelopes to Helen are shown with an address of 1034. But in scenes showing the front door, the address is 346.

Factual error: In the scene where Frank is giving Helen a ride home from the Japanese Restaurant, when they drive across the Golden Gate Bridge, you see them pass three support towers when there are only two on the real bridge. There are also exit signs that disappear just before they pass the third tower.

Continuity: When they all first move into the new house after the wedding, they are scrambling to get settled into their rooms when the lights go out. Helen and Frank hand out candles and Helen asks Greg to take some downstairs. After he heads downstairs, a voice is heard remarking, "Where's 6-blue-B?" According to Frank's chart, Greg is 6-blue-B. Also, the voice-over begins just before the shot switches off of Greg heading downstairs.

Continuity: In the scene where Frank brings Helen home to meet his kids, he asks Mike to fix them a drink. He does, but only fills Frank's glass halfway. When Rusty takes the drinks to them, the glass is full.

Continuity: When the doctor examines Phillip (the first night the whole family is in the new house) he wipes and puts away his thermometer, then does the same motions again.

Continuity: When Helen and Frank go to the bar on their first date, Helen asks Frank to get her some cigarettes. Frank returns with six packs of cigarettes, three in each hand. Helen then claims that she doesn't smoke, and Frank puts all six packs into one hand to accept a drink. When we next see Frank's hand he has three packs of cigarettes. Finally, the cigarettes disappear completely.The cigarettes couldn't have fallen on the floor because we see the floor in different shots. And, as Helen and Frank are standing in the middle of the bar, surrounded by people, Frank has no place to put the cigarettes.
